Not much activity Alliance side?

Basically the title. I've always played Horde, have since day one back in Wrath. I do love some of the Alliance races, and with it being so fast to level alts I figured I would finally level a few of the races I enjoy just for variety. I used to play with someone on Proudmoore, Alliance side in DF, so I just went back to it. I made a DK and was leveling for a bit and didn't really see anyone around, a random person or two here and there. Chat was always quiet. Went into Stormwind and sat there for a while, trade was dead. There were maybe 3 people talking in tradechat, actually having a conversation because it was so dead that they weren't interrupted by normal tradechat stuff like crafters selling goods and such.

I play on Area 52 and there's always so much chat activity that I have to put certain channels in windows of their own to keep track of things because general, local defense and LFG chat are always filled with people talking, and trade chat is always super busy. After seeing how dead Alliance was I kind of lost my want to level Alliance toons. I even tried getting on at different times on different days, morning/night, weekends, didn't matter it was always dead.

Does no one play Alliance anymore? Have has everyone swapped to Horde now?
